Description
Technical field
The utility model relates to a kind of oil-filled transformer pasta level measurement sensor, particularly a kind of oil level indicator.
Background technology
Normal transformer oil level is too low, may cause protection misoperation, time serious, transformer coil or lead-in wire pasta even can be made to expose, cause dielectric breakdown accident.Oil level is too high, then easily cause oil spilling.Except leakage of oil, oil level declines or rises and depends primarily on oil temperature decline or rise.The volume of transformer oil, directly by oil temperature variable effect, causes the pasta of oil ga(u)ge to be elevated, so when charge of oil, and must in conjunction with the proper height selecting oiling when ground temperature.
Be directed to above designed by the too low or too high negative effect of the oil level that arrives, therefore the measurement of oil level seems very important.
This type of oil level indicator exported with high low oil level on the market now all needs charged to power, and this adds cost virtually, also limits the environment for use of this product, cannot use this oil level indicator in power free place.
Summary of the invention
The utility model will solve this type of oil level indicator that crowd exports with high low oil level on the market all needs charged to power, and provides a kind of novel oil level indicator that can export with high and low warning dry contact without the need to power supply.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of oil level indicator, comprises, base, float, the first ring-shaped magnet, the second ring-shaped magnet, positioning pointer, rotating shaft, tongue tube, connection terminal; Described float is connected with the first ring-shaped magnet, for measuring oil level height; Described second ring-shaped magnet, positioning pointer to be all sleeved on outside rotating shaft and to be fixedly connected with rotating shaft; Described positioning pointer is provided with magnet away from rotating shaft end, for controlling tongue tube signal break-make; Described tongue tube is connected with connection terminal.
According to oil level height, float fluctuates, and drives the first annular magnet rotors.First ring-shaped magnet drives the second ring-shaped magnet to rotate by magnetic force.Due to the second ring-shaped magnet, positioning pointer all overcoat be fixed on rotating shaft, when second ring-shaped magnet rotate time, rotating shaft is also rotated thereupon, drive positioning pointer rotate.Positioning pointer is provided with magnet away from rotating shaft end, and tongue tube is then controlled circuit on-off by magnetic force, and when the magnet on positioning pointer top presses close to tongue tube, then circuit is connected, and the connection terminal be connected with tongue tube outputs signal.
Further, described tongue tube is divided into high-order tongue tube and low level tongue tube, is arranged at described positioning pointer both sides respectively, for the high-order and oil level low level alarm at oil level.
When positioning pointer band moving magnet is near high-order tongue tube, under magnet effect, high-order tongue tube circuit becomes path, and level alarm-high signal exports; When positioning pointer band moving magnet is near low level tongue tube, under magnet effect, low level tongue tube circuit becomes path, and level alarm-low signal exports.
Further, also comprise liquid level pointer, rotating shaft is fixed in described liquid level pointer one end, is used to indicate liquid level.
When rotating shaft is rotated under the second ring-shaped magnet drives, liquid level pointer together rotates, instruction liquid level.
Further, described float is connected by metal rocker arm with the first ring-shaped magnet.
Further, described metal rocker arm is also provided with securing member, for metal rocker arm is installed on described base.
Further, described connection terminal is arranged in control enclosure, and described control enclosure is arranged on base side.
Further, described tongue tube is connected by internal connection line with connection terminal.
Further, also comprise panel, described panel is provided with high-order instruction and low level instruction.
Further, described base is also provided with O-ring seal.
The beneficial effects of the utility model are: this oil level indicator can realize the requirement of oil level display and high and low oil level dry contact warning output when non-transformer is powered.Without the need to being equipped with power supply to oil level indicator separately, be applicable to different occasions.
